Dead on at 100yds 4inches right at 400yds

have you tried a tall target test to verify that your scope is making the right adjustments. just because your reticle is level doesn't mean it is accurate when making adjustments.

Yes I did [nightforce atacr]

Plus, the tall target test is to verify your vertical reticle is perfectly level

Does it consistently shoot 4" to the right? Or just one group.

 

[buzzyb]

Not all the time. Like the pics in my first post it happened after I zeroed the scope. The first pic was 400yds I went to 100 yds to zero I made a 1/4 minute change and shot the last pic I posted went to 400 and was 4inches to the right

I'd see what your scope is adjusting like at 400 set it up good and secure in shooting bags and see if it's adjusting properly. I have a new name brand scope that I noticed doesn't adjust properly but it holds it's zero at 100 yards and I risk getting an unrepaired scope back that is "within spec" So I've just left it on. But you may notice some strange stuff going on in yours.

My sig 2400 said to go up 4.86 I went 5 and it was good so I think it is tracking good

Did you use wind flags? You might/will be surprised how much wind there is with the wind flags. Very good indicators at muzzle to target.

So far on every suggestion you have indicated you have it 'covered', which eliminates the rifle. My suggestion is it is either wind or hindering shooting techniques which becomes more pronounced at longer distances. Try having someone else shoot the rifle or use a different shooting position (bench vs prone) for validation.

I agree. I was thinking to myself while reading this thread that a different shooting position should be tried, if shooting from a bench, then try prone. If shooting prone try from a bench. And have another shooter give it a try.

I have been shooting from a bench and working on technique. It's just a bummer when you shoot a 1inch group at 400yds and can't repeat it

 

[nmbarta]

Parallax can do that, I'd assume you've got that right.

 

[buzzyb]

Yup

I would maybe guess that the first group there was a SLIGHT breeze right to left and it canceled your spin drift. It only takes like 1mph to do that. Then maybe today you had 0 wind to a very very slight left to right even if couldn't feel it. Sometimes I think it's basically calm and then pull out the kestrel and see 2-3mph wind speed.
